So in the working draftlike N4892, we could find the coroutine components is defined in stdnamespace instead of std::experimental namespace.And the coroutine support in clang seems to be relatively stable. So Ithink it may be suitable to move the coroutine component into theexperiment namespace now.This patch would make clang lookup coroutine_traits in std namespacefirst. For the compatibility consideration, clang would lookup instd::experimental namespace if it can't find definitions in stdnamespace. So the existing codes wouldn't be break after updatecompiler.And in case the compiler found std::coroutine_traits andstd::experimental::coroutine_traits at the same time, it would emit anerror for it.The support for looking up std::experimental::coroutine_traits would beremoved in Clang16.Reviewed By: lxfind, QuuxplusoneDifferential Revision: https://reviews.llvm.org/D108696 List of files: /llvm-project-15.0.7/clang/test/AST/coroutine-source-location-crash-exp-namespace.cpp Thu, 04 Nov 2021 03:50:30 +0000 Chuanqi Xu <yedeng.yd@linux.alibaba.com>
